The health benefits of owning a pup go far beyond extra exercise. New research shows canines help ward off disease, lower stress levels, and even detect cancer. Here’s a breakdown of how your dog is saving your life.

A dog’s sense of smell is up to 100,000 times more accurate than ours. Canines are being trained to detect the scents of early-onset diseases in humans.

The Eyes

“Imagine looking at your dog and he looks back at you — in about 30 seconds, oxytocin courses through your body,” says psychologist Chris Blazina. This hormone, associated with feelings of trust and bonding, could increase by as much as 300 percent, research suggests.

The Fur

Pet and play with a dog, and your brain soon releases the feel-good endorphins serotonin and prolactin. After 15 minutes, your levels of the stress-hormone cortisol decrease significantly.

The Paws

Service dogs use their paws to dial 911 for a diabetic owner with dangerously low blood sugar or to turn on lights for PTSD sufferers. Dogs also use their paws to comfort us when we’re anxious, similar to giving us a soothing pat on the back.
